' 2 Claims. (01. 221-60) companying drawing that forms a part of'the.

same.

The invention consists essentially of the novel features of constructionpointed out broadly and specifically in the claims for noveltyfollowinga description in detail of an acceptable form of the invention.

The objects of the invention are to devise a closure means for tubes andother containers for retaining liquids and semi-liquids as well as othermatters of a similar nature, e. g., toothpastes, oil tubes, vaselines,shaving creams and innumerable other commercial articles; to facilitatematters for the consumer in enabling him to remove the contents from thetube without getting his fingers smeared, which so often occurs in theuse of ordinary capped tubes; to insure a tight closure for the tube andthe consequent saving of the contents thereof; to eliminate the constantirritation and annoyance caused by the frequent losses of the caps ofthe tubes, and thereinplace substitute a cap that will be a fixed partof the tube itself and at the same time can not only be easily raised orlowered but securely locked in its closed position; to materially reducethe loss of the tube contents owing to the fact that by using thisparticular closure the unused contents of the tubes thatmay stillproject beyond the neck of the tube will be forced back into the tuberather than therearound, when the closure is closed; and generally toprovide a very serviceable, durable and efiicient closure means at theminimum cost, that may be used for many varied purposes.

In the drawing:

Figure 1 is a. perspective fragmentary view of the tube without theclosure means.

Figure 2 is a perspective fragmentary view of the tube with the closuremeans mounted thereon. Figure 3 is an assembly view of the differentparts of the closure shown in perspective.

Figure 4 is an enlarged fragmentary sectional view of the tube with theclosure means mounted thereon.

Figure 5 is an enlarged fragmentary sectional view of the tube andclosure means in right angle to the view .shown in Figure 4.

Like numerals of reference indicate corresponding parts in the variousfigures.

Referring to the drawings, the closure means is in the form of a cap asindicated by the. numeral ll having the lid II and the hinge bearing l2and the central projecting curved boss l3 and the finger grip I4.

The lid II is pivotally secured to the cap l0. by the hinged pin 20. Thecurved boss l3 fits into the can In and into the tube. l5 when the 5 lidl I is turned down on the cap. The cap III has the orifice or groove l6and the smooth vertical surface I! which is engaged by the finger gripH, when the lid is brought down on the cap. 'At the same time the springI8 is pressed down into 10 the orifice or groove IS. The cap isinternally threaded for engagement with the externally threaded neck 19of the tube 2|. The cap II) has the groove 22 adapted to 'receive thespring 18 when the cap is locked to the tube.

All that is necessary is to turn the cap on the neck of the tube untilthe spring l8 engages the recess 22. The curved part of the spring I 8follows the threads on the neck of the tube, and this spring isconsequently forced into the recess 22, thereby locking the cap to thetube.

.For unlocking the closure means, .the cap is simply turned back to itsoriginal position, the spring I8 will then return to the snioothvertical surface 23, on the neck 24 of the tube 2|, and by 25 pressingthe finger grip l4 upwardly the. lid can be raised.

In other words, it is the turning of the cap on the neck of the tubethat locks and unlocks the lid and consequently the cap to the tube. Thecurved boss l3 fits tightly into the neck of the tube and prevents theescape of the contents of the tube during the operation and at the sametime it prevents the contents from becoming hardened due to exposure tothe air.

It will be seen that it is not necessary to remove the cap from thecontainer, the turning of the cap on the neck of the tube will allow thefree use of the contents of the tube when desired.

It is of course understood that the closure 40 means herein describedmay be formed with slight modifications for other purposes apart fromtubes, such as cans, pipefittings, bottles, radiator caps onautomobiles, and on innumerable other objects, without departing fromthe scope of this invention.

What I claim is: 1. In closure means for tubes and the like, a containerhaving a tubular seat member externally threaded and having a verticalsmooth sura spring secured to said lid and having a tongue and adaptedtofit between the tubular member and the cap and to engage with the.groove of the cap in the closed position of the lid.

2. In closure means for tubes and the like, a container having a.tubular seat member externaliy threaded andhavingasmooth surfacebreaking the threads, an internally threaded cap having a verticalgroove on its inner side and engaging with the tubular seat member 0!said container, a. lid hingedly secured to said cap and having a centralprojecting curved boss, a finger grip projecting from said lid, and aspringaecured to said lid and having a tongue and adapted to fit betweenthe tubular member and the cap and to 5 engage with the groove of thecap in the closed position of the lid.
